"His gaze was rich." I really like the way in which the word 'rich' here compliments the 'coin' imagery in the previous line - suggesting that the wealthy man is ruled solely by avarice.

"Spoiling me with extravagant, unnecessary things." Good. I'm glad that you ended this piece with the words 'extravagant' and 'unnecessary' - they show the reader that the speaker is a little affronted by the wealthy man's romantic pursuit of her.
